The INVEST conference, an international meeting to define the scientific goals and technology needed for a new ocean drilling program, was held at the University of Bremen between the 22nd and the 25th of September 2009. Based on the large attendance and vigorous engagement of scientists in the discussion of new science/technology ideas, INVEST was extremely successful. Initially 400 participants were expected, but the INVEST steering and organization committees were thrilled to see a much larger number of scientists flock to Bremen to demonstrate their support and enthusiasm for the continuation of an

international scientific ocean drilling program.

In all, 584 participants, including 64 students, from 21 nations and >200 institutions and agencies attended the INVEST conference. Contributions to INVEST included 103 submitted white papers that are lectures, chosen to highlight overarching themes and new research directions.

The conference was sponsored by the Integrated Ocean Drilling Program Management International (IODP-MI), the Deutsche Forschungsgemeinschaft (DFG) and MARUM research center. The National Program Offices supported travel for many participants.

Working group sessions

The working group sessions were organized within six conference themes. Each meeting attendee was given the opportunity to participate in three working groups: one within conference themes one through three (days 1 and 2), one within conference themes four and five (days 2 and 3), and one within conference theme six (day 3). Up to 18 working groups met in parallel sessions. All working groups within one conference theme met to report to each other the results of the working group discussions. The conference theme co-chairs then met with the working group chairs and scribes to prepare a plenary presentation of the conference theme.
